LRPAP1
LDL receptor related protein associated protein 1 | Alpha-2-MRAP, HBP44, A2MRAP, RAP

This gene encodes a protein that interacts with the low density lipoprotein (LDL) receptor-related protein and facilitates its proper folding and localization by preventing the binding of ligands. Mutations in this gene have been identified in individuals with myopia 23. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

LRPAP1 — as a Regulated Gene

TFs regulating LRPAP1 0 TFs

Transcription factors with Perturb-seq knockdown data for LRPAP1. The Binding column indicates whether any binding evidence exists for this TF–gene pair (ChIP-seq or motif footprint peaks). The Mean coef is the average Perturb-seq regression coefficient across active gRNAs (positive = LRPAP1 upregulated upon KD; negative = downregulated). The Outlier column indicates whether this gene is in the top or bottom 5% of all TF knockdown effects.

Elements linked to LRPAP1

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of LRPAP1, linked by TSS proximity or chromatin conformation (Multiome / HiCAR). Each element overlaps at least one TF ChIP-seq binding site — the TFs column shows how many distinct TFs bind that element.
